Unstable with Virtual Servers when running Active/Standby F5 Big-IP LTM 3600 ver 11.1

Dear Trungleon,

 

I will prefer you to do the following as first step kick out of the of boxes completely from the network and let all of the operations run from unit1 . If it goes fine kick out unit1 and bring in unti2 and checkthe same. If this process shows any disconnection or problem then you may have a problem in network as well.

 

At first place what is the reason tha two boxes are licensed differently... and lets say even if they are licensed differently are both the modules LTM& ASM provisioned on Unit 1 or not if its only LTM module provisioned on both of the modules then it should work fine... If the boxes have different modules provisioned them make it same for both of the boxes. Are you not using serial cable for fail-over that only the network disruption is causing fail-over. If you are using only network fail-over and there is no serial cable avaliable then try to configure it on a separate port and see if it works fine.

 

If you have done any Mac-address binding on the Firewall level remove it.

 

 

Regards,
